Abstract: In order to study occurrence characteristics of system faults in SFEP, a method to determine target event state and probability was established based on SFN and quantum game theory. Game hypothesis was established based on safe and unsafe behaviors of managers and operators, hybrid strategy probability was represented by quantum mechanics. Then, probability of single event hybrid strategy, quantum game representation of event logic relationship, form of target event state and occurrence probability were studied. The results show that by using static game between manager and operator to determine expected benefits, by derivation can obtain probability of safe and unsafe behaviors of all parties, and obtain probability of all states of target event. However, because benefits of manager and operator determine probability of safe and unsafe behaviors, so probability of all states of target event is not accurate.

Key words: system fault evolution process (SFEP), target event state, occurrence probability, quantum game, space fault network (SFN)
